BASIC.SYSTEM without text file support

[oliverschmidt]

Hi,

Adding new features (like #36) to BASIC.SYSTEM is anticipated to be somewhere between very hard and plainly impossible.

On the other hand BASIC.SYSTEM has a feature set that I think almost all users nearly never make use of. It's the set of file I/O commands to be used from within BASIC programs also known as text files.

I presume that removing support for OPEN, CLOSE, READ, WRITE, APPEND, FLUSH and POSITION would free up quite some space inside BASIC.SYSTEM.

The current BASIC.SYSTEM with text file support should be made available as part of ProDOS with a different name (i.e. BSCFILES.SYSTEM or BASICFIL.SYSTEM or BASICFILEIO.SYS) to be explicitly used for the (seldom) scenario of running a BASIC program that makes use of file I/O.

Thanks for considering,
Oliver
